I believe the answer is:
relish
'to enjoy' is the definition.
(synonyms)
'part in quarrel is hateful' is the wordplay.

(Other definitions for relish that I've seen before include "Great delight" , "Enthusiastic enjoyment of a condiment" , "what goes on food" , "'Take pleasure in, savour (6)'" , "fancy" .)
